在铸造厂的所有开支中以生产用材料费所占比重最大,约在50%以上。要想少投资,多获利,就必须以最少的投料,获得最多的合格铸件。如何做到这一步,这就是本文要阐述的内容。一、几个炉念1．金属炉料有效率LyLy=钢水(或铁水等)重量×100%…(1)金属炉料重实际上Ly=1－烧损率2．钢水(或铁水等)利用率LL在铸造生产过程中,由于操作不当或生产安排不合理等原因,钢水(或铁水等)不能100%被利用,为此提出了钢水利用率概念。
In all the foundries in the expenditure of production materials, accounting for the largest share of about 50%. To invest less and profit more, you have to get the most qualified castings with the least amount of material. How to do this step, this is what this article should elaborate. First, a few furnace read 1. Metal charge efficiency LyLy = molten steel (or molten iron, etc.) weight × 100% ... (1) metal charge weight actually Ly = 1- burn rate 2. Utilization rate of molten steel (or molten iron, etc.) LL In the casting process, molten steel (or molten iron, etc.) can not be used 100% due to improper operation or unreasonable production arrangement. Therefore, the concept of molten steel utilization rate is proposed.
